General Comments:

1998Am04 (also 1995AmZY,1992WeZX): 75Ni identified after the 9Be(86Kr,X) reaction at E=500 MeV/nucleon with a 2 g/cm2 target. Bρ-ΔE-tof technique used, β particles detected.

2010Ho12 (also 2005Ho08): 75Ni identified in the 9Be(86Kr,X) reaction at E=140 MeV/nucleon with a 376 g/cm2 target. Fully-ionized 86Kr beam, A1900 fragment separator at NSCL facility using Bρ-ΔE-Bρ method. After separation, the mixed beam was implanted into the NSCL β-counting system (BCS) consisting of stacks of Si PIN detectors, a double-sided Si strip detector (DSSD) for implantation of ions, and six single-sided Si strip detectors (SSSD) followed by two Si PIN diodes. The identification of each implanted event was made from energy loss, time-of-flight information and magnetic rigidity. The implantation detector measured time and position of ion implantations and β decays. Neutrons were detected with NERO detector. Measured β- and βn-correlated events with ion implants, half-life of 75Ni and delayed-neutron emission probability. α total of 1905 implants were detected, and 43 correlated βn coincidences were observed.

Theoretical calculations (half-life, %β-n): 1989Kr02, 2002Gr16, 2005Gr29, 2005Bo19, 2008Ma17.

Q-value: S(2n)=10280 300, S(2p)=36210 760, Q(β-n)=3690 300 (syst,2012Wa38).

Q-value: Estimated uncertainties (2012Wa38): 300 for Q(β-), 500 for S(n), 670 for S(p) and Q(α).
